Can this combat fakes?

[Goodwatch]

Hublot are about to introduce a new system to combat fakes. From a certain date, all watches will come with credit card like pass. The pass contains a hologram, other safety features, a serial number and a link to a special website. With the serial number you can check the watch's authenticity on the website. Only Hublot knows the authentic serial numbers and they are registered in a database. The serial number also tells what type of watch it is.

This could be a first step to combat the 'legitimate' sale of fakes although it can do nothing about the sale of street corner fakes. But if someone offers a 'real' Hublot on eBay, all you have to do is check the serial number before you purchase it.

Do you think this can work?
